I think Universal is now going to become the go-to park in Orlando. It is only a matter of time. With the new Harry Potter additions opening up Disney won't compete with them.
Hang on, that's a post I read in 2010.
Okay, in all seriousness, this is a good thing. Competition breeds intensity. It will keep Disney on their toes. They don't need to be, because their attendance is still crushing Universal, but it is like being a star QB in the NFL but having a back-up on your team waiting for you, just in case. I don't know why people don't think this is a good thing for Universal to improve as well.
But at the end of the day Disney gets me back to their parks because of things like nostalgia, attention to detail, history, uniqueness, fantasy and allowing me to feel disconnected from things for a day. Also bringing back memories. As long as that never changes with Disney and they don't screw it up, they'll continue to be the standard. I know where the thrills are, and I love them too, but it still doesn't top the experience of Disney.
